#include <wctype.h> int iswctype(wint_t wc, wctype_t charclass);
The iswctype() function returns a boolean value that indicates whether a wide character wc is in charclass. The behaviour of the iswctype() is undefined if the iswctype() function is called with an invalid charclass (changes of LC_CTYPE category invali- date charclass) or invalid wide character wc. The behaviour of the iswctype() is affected by the LC_CTYPE category of the current locale.
The iswcttype() returns: 0 wc is not in charclass. non-zero wc is in charclass.
No errors are defined.
